The antimicrobial activities of aqueous ethanol and chloroform extracts of three Baccharis species currently used in Northern Chile folk medicine for the treatment of several infectious and inflammatory disorders were tested against Gram-positive and negative bacteria and fungal spp. using the agar-disc diffusion assay. The results indicated that the activity was more pronounced against Gram-positive than against Gram-negative bacteria and yeast. No significant differences on the antibacterial activity were observed in the aqueous ethanol versus chloroform extracts. None of the plant extracts evaluated exhibited any activity against ten fungi tested.
对智利北部民间医学中目前用于治疗多种感染性和炎症性疾病的三种巴卡里斯属植物的水乙醇提取物和氯仿提取物,采用琼脂平板扩散法测试了其对革兰氏阳性菌、革兰氏阴性菌和真菌的抗菌活性。结果表明,其对革兰氏阳性菌的活性比对革兰氏阴性菌和酵母菌更显著。水乙醇提取物和氯仿提取物的抗菌活性未观察到显著差异。所评估的植物提取物对测试的十种真菌均未表现出任何活性。
